Cloudflare Workers enables developers to run JavaScript, TypeScript, and WebAssembly at Cloudflare’s global edge network. It is well suited for deploying lightweight services and inference pre-processing close to end users to reduce latency and offload centralized model servers.
Key Features
- Global edge deployment for millisecond-scale latency.
- Supports JavaScript/TypeScript, WebAssembly, and multiple runtime adapters.
- Native integrations with Cloudflare KV, Durable Objects, and R2 for low-latency storage.
- Built-in routing, HTTP API handling, WebSocket support, and scheduled triggers for edge-driven AI workflows.
Use Cases
- Move inference preprocessing to the edge to reduce central model calls and bandwidth.
- Implement real-time inference routing, personalization, A/B testing, and security filters.
- Build lightweight microservices, API gateways, and CDN-accelerated AI frontends.
Technical Highlights
- Serverless, pay-as-you-go model suitable for bursty workloads.
- Low cold-start and high concurrency via the Workers runtime.
- Composable edge storage (KV, R2, Durable Objects) for fast data access.
- Offload prompt engineering and request filtering to the edge to optimize overall system cost.
